Oil and filter recommendations

[avalonandl]

FOODFIGHT !!!!! said Bluto in Animal House

I mean oil fight....LOL not really

Swath- i posted my own preferences-opinions.... just to get a reaction.....

The M1 filters are very good... and pricey.....

I honestly don't remember what tests... It was on Offshoreonly.com several years ago.... and there are a gillion grades of oil....

It was fun to read because some sacred cows got really BAD numbers...... Amsoil - cough cough....

Yeah I don't buy into the Amsoil hype. Caused cam failure on a couple of our 'company' cars; 2011 - 2012 Dodge Chargers.

Have always used Mobil 1 until this vehicle. This Tahoe was bought used at a dealership and all maintenance was done there with AC Delco synthetic so I stuck with that.

Found this vid interesting.

Right now I am running Baldwin B160 Filter with 5w30 Valvoline Hi-Mileage Syn-Blend on my 2007 Yukon XL 2500 with the LY6 6.0L. Seems to work well so will most likely stay with this setup

It is hard to say anything bad about WIX filters. Have used for many years on vehicles and my Harley's years ago.

What type of oil pressure are you getting? I’ve got the same rig.

I have used Mobil 1 5W-30 for the 75k miles of ownership I have owned mine. Used AC Delco filter throughout as well except one time when I used a Mobil 1 Extended Performance (Gold strip) filter and my oil sensor went bad. Possible coincidence but I stayed with AC Delco after that. Changed oil atleast 3 times before and over 3 times after that incident.

just a coincidence :O

I would not trust a paper filter i think it would blow out at 70PSI?

just don't leave the E series filters in more then a year unless you want paper sludge..

I get about 50 cold, 40 warm with driving and 30 warm at idle.

I think the previous owner had oil pump or pickup seal work done before I bought it because at warm idle I am at 50 psi and higher rpm is at at least 60 psi.

I would think there is something wrong with my engine if it was that low



70-75PSI cold (seen as high as 80PSI) 55-60PSI warm driving 45-50PSI idle....

My car sits at 35 idle and 40 regular driving. If I go hard, it might touch 50-60. I think a few confirmed these numbers on the TBSS while the TBS normally had an average higher pressure.

40 warm while driving

Slightly over 30 warm at idle

I’ll see about a cold start tomorrow. Don’t really pay attention.

And you’ve got the same truck with the 6.0 ?

I would think so. I haven’t really come across anyone with your numbers. And I ask around out of curiosity.

yeah 6.0L it has a specialty oil pump though (similar as the LT1 corvette)

his is a "fixed" pump

this is a Variable-displacement oil pump.

What 6.0L do you have? Every NNBS I've owned had just about the same numbers listed.

Found this on another forum. It appears my oil pressure is on par for an LY6 6.0L:

For oil pressure it depends what engine you have for the specs engine hot

L76
1,000 RPM 24psi min.
2,000 RPM 35psi min.
3,000 RPM 38psi min.

*LY6*
1,000 RPM 22psi min.
2,000 RPM 30psi min.
3,000 RPM 33psi min.

For both engines the AFM relief valve oil pressure - as measured at oil sensor location:
Max. 55-75 psi

GM went to the future and came back with the variable oil pumps ..


If you google viable displacement oil pumps it will only refer back to 2012 as being new tech.

it's a high performance oil pump for the Lxx engine

it's a frankenstein LS2 based engine RPO LFA and LZ1


It’s available under p/n 12625823 for the LFA and p/n 12623423 for the LZ1

apparently it saves 2 HP from being wasted


HP is
332 hp @ 5100 RPM(248 kW) 367 lb⋅ft (498 N⋅m)4100 RPM Combined output is 379HP/ 472 lb-ft..

some people might consider this a VERY HIGH OUTPUT engine lol

VHO 6.0L


it has a 4 or 5" aluminium drive shaft it's big though i'll measure it later
